Embodiments of a system and method for automatic context sharing across multiple devices are generally described herein. In some embodiments, an application context information transfer technique is provided that is capable of detecting when the user is moving away from or towards a stationary or fixed-location computing device, and transferring application context information to or from a mobile device. The application content information transferred between devices may include information that allows the user to continue a computing device activity on the mobile device or continue mobile device activity on the computing device, such as editing a document, reading a website article, or viewing a streaming video. The techniques described herein may be used to automate the transfer of such application context information between devices.
